The tubvis Provided with standard legs 4 connected by enlarged detailedsectional p plan 7 wlth 'a drain nipple 3, the same belngnormallyclo'sed by a-stopper suitable cross braces 5, the said legs by.their arrangement defining an interior space {or} circle within whichthe driving motor and i plane of the machine,

with the end Of said tubular bearing.

. spectivel all of the connected operating parts are disposed, so thatnone of such operating elements project beyond the circumferential andconsequently are thus enclosed and protected from injury by contact withextraneous objects. I One of the legs has by means of screws 6'. Passingaperture of the strap is a thumb screw 7, which thumb screw is inthreaded union with an aperture in a motor 9. The base ring of the motor1salso formed with apertures 6", f whic apertures isfitted over aretaining screw 6 and the' other aperture over a lug 8', which extendsfrom the juxtaposed face of the strap 6. The motor 9 is thus rigidly-butdetachabl) secured to the leg of the tub by; a single thumbscrew 7Hence, the assem lage can readily be effected and a standard motor canbe utilized having its shaft provided with a vertically disposed pulley9 for direct drive connections. I

It is understood that the bottom and side walls of the tub may becorrugated'in' any suitable manner -to facilitate washing, thecorrugations being not shown as they form no part of my invention.

The center for the reception of the screw threaded end of atubular-bearing or housing 10, the said bearingbeing provided with ashoulder 10 that is fitted snugly against the upper surface of the tubbottom. The/bearing 10 is firmly, fitted in ,its vertical position and.the joint between it and the bottom is sealed by a binding nut 11,whichnut is in threaded union tubular hearing or housing 10 is providedfor the reception of a spindle 12, the lower end of which extendstherethrough for the rece tion ofa spoke driving pulley 13. The, driiungpulley 13 is, struction, built up 7 having a metallic band or felly 15secured to thelr outer ends, which band, in turn, has soldered thereon abelt receiving metallic ring 15'. Hence the belt receiving ring -'isreinforced and the pulley, as a whole, is

cheaply constructed and light. I t

The spokes 14 of the pulley are in mitered connection at their centralintersection, at which point they are apertured for the reception of thethreaded end 12 of the spindle 12. The spokes and pulley, as a whole,are held in rotative relation with the spindle by upper and lowerclamping nuts 16 -16' rethere being suitable washers interposed tweenthe upper clamping nut and the lower end of the "assocla'ted tubularbear.-

in 10 to spindle. v

The upper end of the spindle 12 projects through the tubular bearing 10,and in order to effect a water tight joint at this point, a

limit longitudinal play of the fixed to its inner surface, a strap 6through an" base ring 8 of an electr1c"19, -whichspokes are centrallyapertured h th-imble 20, the said thimble of the tub bottom is aperturedgage and gently 12, through action,

disk constituting side walls of perforated rnaterial, the'upper edges ormbuth portion of which areconbox 17 is provided, the same being inthreaded union with the en tubular bearing; The power driven spindle 12has rigidly secured thereto, at its upper end, a disk 18 from whichextends a cran pin 18, as shown in Figure 1. 'When the machine isequipped for washing, the crank pin .18 has loosely mounted thereon, askeleton agitator A. The agitator is constructed from cross connectedwood spokes or threaded end of a eing clamped to thespokes by upper andlower nuts 21, whereby the spokes ofthe agitator are secured togetherand a metallic hub is formed, which hub is, as shown, detachably mounteupon the crank pin-18", to thereby produce a metal to metal contactbetween the drive and driven elements," it being understood that thelower clamping nut 21' also forms a thrust bearing.

bearing .10. Thereafter the agitator is as shown in Figure dropped intoposition,

22, depend- 1, and a series of rounded fingers ing ,fromthe spokes ofthe agitator,'will enpress upon the clothing at.

various .points. Hence the agitator is capable ofv horizontal play orwhat might be termed, a floating action with relation to its wrist pinconnection 18. i 1 c When motion is imparted to the spindle the beltdrive connection to the motor, the agitator wilhdescribe awa due to theeccentric driving connection with the spindle, whereby the agitator hasa planetary movement of rotation aboutits.axis. Hence-the fingers 22will describe a series of independent rotary gyrations, impartingthereto a multiple series hing actions upon. the surface of thecloth-'ving thereto a massaging gentle movethe continued action imparted tothe agitator, whereby the clothing will be constantly shifted withrelation to its position in the tub. A wringing or drying basket C isthen substituted-in the machine for the agitator and the wet. fabricsplaced a metallic the bottom thereof, having is preferably constructedfrom tractedinward a to nested therein prevent the clothing bble ofscrubp as a whole, will cause it to move ma rotatory direction v thereinfor sub-- lectlon to y g peration. This basket om being discharged, by.

centrifugal action imparted to the basket.

The solid bottom of the basket has a metallic basket bottom has securedthereto a plate 24,

which plate has extending therefrom a pair f coupling pins that arearranged e uidistant from the hub aperture. Hence w en it is desired tofit the basket to the driving spindle of the tub, the operator adjuststhe hub 23- of the basket to the crank pin 18, and in so doing, thebasket is rotated about the pin in such position that an indicatormarkupon the end of the crank pin 18' will register -with acorresponding indicator mark upon the end plate of the hub 23. When thisregistration is effected, the pins 25 are positioned to' straddle thewrist pin disk 18, whereby the basket is locked against rotation uponthe crank pin 18', and is centered axially with respect-to the spindle12. Inasmuch as the horizontal plane in which the upstanding extractor Crotates is above that in which'the depending agitator or dolly Arotates, it is not necessary to empty the water after washing and beforedryin the fabrics, but the water in the tub may fie used in a succeedingoperation, if serviceable' After the clothin which has been previouslywashed, is ropped into the basket, motion being imparted thereto willcause said basket to revolve at a high speed through its directconnection to the spindle and in its rotations, the basket will developa centrifugal force, whereby the clothing is caused to shift outwardlyagainst the walls of said basket. This action of the clothing willefl'ectually extract all water therefrom. The dried clothes can then beremoved and ironed if desired.

Attention is also directed to the fact that the cover B of the tub isformed from a single piece of metal, having a downturned annular lip 26and acircular bead 26, which bead effects a nested seat with relation tothe inner edge of the tub mouth, whereby a comparatively tight joint isefiected and the downturned lip 26 serves as a'protection and it alsopresentsa sightly appearance, whereby it will present a neat appearancewhen, not in use. The removable metallic -top can thus be used for aseat, table or drive mechanism other purposes incidental to householdconveniences. r

While we have shown and described a simple exemplification of ourinvention minutely as to detail, it is understood that we may vary thedetails of construction, within the scope of the claims, as it may behereafter interpreted by the skilled mechanic.

What we claim and desire to secure b Letters Patent of the UnitedStates, is:

1. A washing machine comprising a leg supported tub, a tubular bearinextending the tub, a

upwardly throu h the bottom 0 in the tubular bearing, a

spindle mounte for the spindle, the same being positioned under the tubbottom and located within the le whereby the drivin me hanism isprotected, a crank pin extending upwardly from the spindle, and anagitator detachably mounted upon the crank Cpin, the agitator includinga series of depen ing fingers.

2. A washing machine comprisin a tub with its supporting legs, a tubularearing vertically mounted in the tub, a rotatin spindle supported forrotation in the said bearin drivingmeans for the said spindle locate atthe underside of the tub, a demountable agitator upon the upper end ofthe spindle, and an eccentric connection between the spindle and thesaid agitator whereby a. planetary movement is imparted to the latter.

3. A washing machine comprisin a tub and supports therefor, a tubularearing passing through and secured to the bottom of the tub, a spindlesupported by and mounted for. rotation in the said bearing, a motordisposed at the underside of the tub,
